【発明の属する技術分野】
本発明は、新規な外観と風合いを有するパイル編地の製造方法に関するものである。
【０００２】
【従来の技術】
従来より、パイル編地のパイル面の外観に変化を与える方法としては、パイル編地のパイルの長さを変えたり、パイル面に起毛を施したり、蒸気をあてたりするなど特別な加工手段で編地に手を加える方法があったが、これらは古くから実施されてきた方法で新規な表面感を与えるものではなかった。一方最近のトレンドとして編地の外観変化が強く求められ、平坦な表面から不均一な凹凸のある外観が求められてきた。従来編地の表面を凹凸にする方法として、編機上でパイルをカットしても粒状のパイル編地を得る方法もあったが、凹凸は均一で不規則な凹凸を有するパイル編地でなく、求められる新規性のあるものではなかった。
【０００３】
【発明が解決しようとする課題】
本発明は、この様な現状に鑑みて行われたもので、従来にない不規則な粒状の凹凸外観を有するパイル編地の製造方法を提供することを目的とするものである。
【０００４】
【課題を解決するための手段】
本発明は、上記目的を達成するもので、パイル用糸条として、イソフタル酸と２．２−ビス〔４−（２−ヒドロキシエトキシ）フェニル〕プロパンとを共重合したコポリエステルと、ポリエチレンテレフタレートとをサイドバイサイド型に組み合わせて複合紡糸することにより得た潜在捲縮性フィラメント糸と、ポリエチレンテレフタレートからなる非潜在捲縮性フィラメント糸との複合糸を用いて、編み上がり時のパイルの高さが３ｍｍ以上であるパイル編地を編成し、潜在捲縮性フィラメント糸の捲縮を発現させる１００℃以上の熱水処理を含む仕上げ加工を施すことを特徴とする、パイルの高さ、径及び並び方が不規則な粒状の凹凸外観を有するパイル編地の製造方法を要旨とするものである。
【０００５】
【発明の実施の形態】
以下、本発明について詳細に説明する。
本発明においては、パイルを形成するパイル用糸条として、潜在捲縮性フィラメント糸と非潜在捲縮性フィラメント糸の複合糸を用いる。複合糸の一構成要素である潜在捲縮性フィラメント糸とは、熱処理により潜在化していた捲縮が発現するフィラメントからなる糸条であって、沸騰水にて３０分間処理した後の捲縮率が３０％以上である捲縮を発現する潜在捲縮性能を有するものであるのが好ましい。本発明における捲縮率は、次の方法で測定されるものである。まず、１／１０ｇ／デニールの張力下で、枠に１０回巻いて輪になった糸条を１／６０００ｇ／デニールの荷重下で３０分放置した後、この状態を維持したまま沸騰水中に入れ、３０分間放置する。沸騰水から取り出した後、２４時間標準状態にて風乾し、１／５００ｇ／デニールの荷重をかけて長さａを測定、次に荷重を外し、１／２００ｇ／デニールの荷重をかけてその長さｂを測定し、次式により算出する。
捲縮率（％）＝〔（ｂ−ａ）／ｂ〕×１００
【０００６】
このような潜在捲縮性フィラメントは、互いに相溶性がある２つの熱収縮特性の異なるポリマーをサイドバイサイド型や偏心芯鞘型に組み合わせて複合紡糸することにより得ることができる。潜在捲縮性フィラメントがポリエステル系繊維の場合には、重合度の異なる２種のポリエチレンテレフタレートを組み合わて用いたり、エチレンテレフタレート単位に対して、イソフタール酸を共重合したコポリエステル、イソフタール酸と２．２−ビス〔４−（２−ヒドロキシエトキシ）フェニル〕プロパンを共重合したコポリエステル、スルホイソフタール酸を共重合したコポリエステル等の共重合ポリエステルとポリエチレンテレフタレートとの組み合わせで複合紡糸したフィラメントを用いることができる。
【０００７】
本発明における非潜在捲縮性フィラメント糸は、前記の捲縮率が０であるか、数値として出ても５％以下の糸条である。このようなフィラメント糸としては、通常のポリエステルやナイロン等の合成繊維のフィラメント糸が挙げられる。 本発明における複合糸は、潜在捲縮性フィラメント糸と非潜在捲縮性フィラメント糸とをインターレース加工にて交絡させたり、合撚したり，一方を芯にして他方でカバリングしたりして得る。
【０００８】
本発明では、シンカーパイル編機やダブルニット編機等のパイルを形成する編機で、上記の複合糸がパイル用糸条として用いて、ループパイルやカットパイルを形成したパイル編地を編成する。本発明の特徴を顕著に発現できるのは、ループパイルの場合であり、編み上がり時のパイルの高さが３mm以上であるのが好ましい。
【０００９】
本発明において、グランドを編成する糸条としては、特に限定するものではなく、パイルを形成させる複合糸、潜在捲縮フィラメント糸, 非潜在捲縮フィラメント糸、仮撚加工糸等の糸条のうちいずれの糸条を用いてもよい。
本発明においては、上記のようにして得たパイル編地に、潜在捲縮性フィラメント糸の捲縮を発現させる熱処理工程を含む仕上げ加工を施す。仕上げ加工において、パイルのシャーリングを行う場合には、この熱処理工程の前に行う。潜在捲縮性フィラメント糸の捲縮を発現させる熱処理工程としては、１００℃以上の熱水で処理するのが好ましく、染色加工を行う場合には、染色工程と同時に行ってもよい。この熱処理工程において、潜在捲縮性フィラメント糸が捲縮を発現するときに、片端がフリーとなったパイルが丸まるが、非潜在捲縮性フィラメント糸と複合されているため、均一に丸まらずに不規則な粒状の凹凸のあるパイル面を形成する。このようにして出来上がったパイル編地は、パイルの高さ、径及び並び方が不規則で粒状の凹凸を有した外観を呈している。
【００１０】
【作用】
本発明のパイル編地は、潜在捲縮性フィラメントと他の熱可塑性マルチフィラメントの複合糸で構成されているために編地の熱処理工程において、潜在捲縮性フィラメントがスパイラル捲縮形態をとろうとして、応力が発生しこのために片端がフリーとなったパイルが丸まる時、非潜在捲縮性フィラメント糸による抵抗のため均一に丸まらずパイル面に不規則な粒状の凹凸を発現し、凹凸外観を有するパイル面を得ることができる。
【００１１】
【実施例】
次に本発明を実施例により具体的に説明する。実施例における編地の評価は下記の方法によって行った。
実施例１
パイル用糸条として、イソフタル酸８モル％と２．２−ビス〔４−（２−ヒドロキシエトキシ）フェニル〕プロパン５モル％とを共重合した極限粘度〔η〕０．０５の共重合ポリエステルを第一成分、極限粘度〔η〕０．６８のポリエチレンテレフタレートを第二成分として複合比１：１で複合紡糸、延伸して得たサイドバイトサイド型の潜在捲縮性フィラメント糸１００デニール／２４フィラメントと、極限粘度〔η〕０．６８のポリエチレンテレフタレートからなる非潜在捲縮性フィラメント糸７５デニール／３６フィラメントをインターレース混繊した複合糸を用い、グランド部分には、ポリエチレンテレフタレートからなるポリエステルフィラメント糸１５０デニール／４８フィラメントの仮撚加工糸を用いて、福原精機株式会社製丸編機（ＬＣＰ３０”×２２Ｇ）にてパイル高さが４mmのカットパイルを形成したパイル編地を編成した。得られた編地を１３０℃×６０分の染色加工を含む通常のポリエステルの染色仕上げ加工を施し、パイルの高さ、径及び並び方が不規則な粒状の凹凸外観を有する本発明によるパイル編地を得た。
【００１２】
比較例１
実施例１において、潜在捲縮性フィラメント糸に代えて、ポリエチレンテレフタレートからなる非潜在捲縮性フィラメント糸１００デニール／２４フィラメントを用いること以外は実施例１と同様にして比較例のパイル編地を得た。得られた編地のパイルは、均一な立毛状の外観のパイルであり不規則な粒状の凹凸のパイル表面は構成しなかった。
【００１３】
【発明の効果】
本発明によれば、スプリング状の捲縮にさらに、複雑でかつ細かな捲縮形状を呈する複合糸でパイル編地のパイル面を構成するので、パイルの高さ、径及び並び方が不規則な粒状の凹凸外観を有し、新規な凹凸の手触り感を有するパイル編地をえることができる。[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a method for manufacturing a pile knitted fabric having a novel appearance and texture.
[0002]
[Prior art]
Conventionally, as a method of changing the appearance of the pile surface of the pile knitted fabric, special processing means such as changing the pile length of the pile knitted fabric, raising the pile surface, applying steam, etc. Although there were methods for modifying the knitted fabric, these methods have not been given a new surface feeling by methods that have been practiced for a long time. On the other hand, as a recent trend, a change in the appearance of the knitted fabric is strongly demanded, and an appearance having uneven unevenness from a flat surface has been demanded. Conventionally, as a method of making the surface of the knitted fabric uneven, there was a method of obtaining a granular pile knitted fabric even if the pile was cut on a knitting machine, but the unevenness was not a pile knitted fabric having uniform and irregular unevenness. It was not something that was sought after.
[0003]
[Problems to be solved by the invention]
The present invention has been made in view of such a current situation, and an object of the present invention is to provide a method for producing a pile knitted fabric having an irregular granular uneven appearance which has not been conventionally provided.
[0004]
[Means for Solving the Problems]
The present invention achieves the above object, and as a pile yarn, a copolyester obtained by copolymerizing isophthalic acid and 2.2-bis [4- (2-hydroxyethoxy) phenyl] propane, polyethylene terephthalate, the used a latent crimpable filament yarns obtained by composite spinning in combination in a side-by-side type, a composite yarn with a non-latently crimpable filament yarns made of polyethylene terephthalate, 3 mm height of the pile during knitting up The pile height, diameter, and arrangement method are characterized by knitting a pile knitted fabric as described above, and performing a finishing process including a hot water treatment at 100 ° C. or higher that causes crimping of the latent crimpable filament yarn. The gist of the present invention is a method for producing a pile knitted fabric having an irregular grainy appearance.
[0005]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, the present invention will be described in detail.
In the present invention, a composite yarn of latent crimpable filament yarn and non-latent crimpable filament yarn is used as a pile yarn forming the pile. The latent crimpable filament yarn, which is one component of the composite yarn, is a yarn composed of filaments that manifests crimps that have been latentized by heat treatment, and the crimp rate after 30 minutes of treatment with boiling water It is preferable to have a latent crimping performance that develops a crimp of 30% or more. The crimp rate in the present invention is measured by the following method. First, under a tension of 1/10 g / denier, a yarn wound in a frame 10 times and left in a ring was left under a load of 1/6000 g / denier for 30 minutes, and then placed in boiling water while maintaining this state. Leave for 30 minutes. After taking out from boiling water, air-dry in standard condition for 24 hours, measure the length a by applying a load of 1/500 g / denier, then remove the load and apply the load of 1/200 g / denier B is measured and calculated by the following equation.
Crimp rate (%) = [(ba) / b] × 100
[0006]
Such latent crimpable filaments can be obtained by performing composite spinning by combining two mutually compatible polymers having different heat shrinkage properties in a side-by-side type or an eccentric core-sheath type. When the latent crimpable filament is a polyester-based fiber, two types of polyethylene terephthalate having different degrees of polymerization are used in combination, or a copolyester obtained by copolymerizing isophthalic acid with respect to an ethylene terephthalate unit; Uses a filament that is composite-spun with a combination of a copolyester such as a copolyester copolymerized with 2-bis [4- (2-hydroxyethoxy) phenyl] propane or a copolyester copolymerized with sulfoisophthalic acid and polyethylene terephthalate. be able to.
[0007]
The non-latent crimpable filament yarn in the present invention is a yarn having the above-mentioned crimp rate of 0 or 5% or less even if it comes out as a numerical value. Examples of such filament yarns include filament yarns of synthetic fibers such as ordinary polyester and nylon. The composite yarn in the present invention is obtained by interlacing the latent crimpable filament yarn and the non-latent crimpable filament yarn by interlace processing, twisting them, or covering one with the other as the core.
[0008]
In the present invention, in a knitting machine for forming a pile such as a sinker pile knitting machine or a double knit knitting machine, the above-mentioned composite yarn is used as a yarn for pile, and a pile knitted fabric in which a loop pile or a cut pile is formed is knitted. . The feature of the present invention can be remarkably exhibited in the case of a loop pile, and the pile height at the time of knitting is preferably 3 mm or more.
[0009]
In the present invention, the yarn for knitting the gland is not particularly limited. Among yarns such as a composite yarn for forming a pile, a latent crimped filament yarn, a non-latent crimped filament yarn, and a false twisted yarn Any yarn may be used.
In the present invention, the pile knitted fabric obtained as described above is subjected to a finishing process including a heat treatment step for expressing the crimp of the latent crimpable filament yarn. When the pile is sheared in the finishing process, it is performed before this heat treatment step. As the heat treatment step for expressing the crimp of the latent crimpable filament yarn, it is preferable to perform the treatment with hot water at 100 ° C. or higher, and when performing the dyeing process, it may be carried out simultaneously with the dyeing step. In this heat treatment process, when the latent crimpable filament yarn develops crimp, the pile that is free at one end is rounded, but it is not uniformly rounded because it is combined with the non-latent crimpable filament yarn. A pile surface with irregular granular irregularities is formed. The pile knitted fabric thus completed has an appearance in which the pile height, diameter, and arrangement are irregular and have grainy irregularities.
[0010]
[Action]
Since the pile knitted fabric of the present invention is composed of a composite yarn of a latent crimpable filament and other thermoplastic multifilament, the latent crimpable filament will take a spiral crimped form in the heat treatment process of the knitted fabric. As a result, when a pile that is stressed and thus free at one end is rounded, it is not rounded uniformly due to the resistance of the non-latent crimpable filament yarn, and irregular grainy irregularities appear on the pile surface. The pile surface which has can be obtained.
[0011]
【Example】
Next, the present invention will be specifically described with reference to examples. The evaluation of the knitted fabric in the examples was performed by the following method.
Example 1
As a pile yarn, a copolymer polyester having an intrinsic viscosity [η] of 0.05 obtained by copolymerizing 8 mol% of isophthalic acid and 5 mol% of 2.2-bis [4- (2-hydroxyethoxy) phenyl] propane Side bite side type latent crimpable filament yarn 100 denier / 24 filaments obtained by composite spinning and drawing with a first component, polyethylene terephthalate of intrinsic viscosity [η] 0.68 as a second component at a composite ratio of 1: 1 And a non-latent crimped filament yarn of 75 denier / 36 filaments composed of polyethylene terephthalate having an intrinsic viscosity [η] of 0.68, and a polyester filament yarn 150 composed of polyethylene terephthalate in the ground portion. Made of Fukuhara Seiki Co., Ltd. using denier / 48 filament false twisted yarn A pile knitted fabric with cut piles with a pile height of 4 mm was knitted with a machine (LCP30 "x 22G). The resulting knitted fabric was dyed and finished with ordinary polyester, including dyeing at 130 ° C for 60 minutes. Thus, a pile knitted fabric according to the present invention having a grainy irregular appearance with irregular pile height, diameter and arrangement was obtained.
[0012]
Comparative Example 1
In Example 1, instead of the latent crimpable filament yarn, a non-latent crimpable filament yarn 100 denier / 24 filament made of polyethylene terephthalate was used in the same manner as in Example 1 except that the pile knitted fabric of the comparative example was used. Obtained. The pile of the obtained knitted fabric was a pile having a uniform nap-like appearance and did not constitute a pile surface with irregular granular irregularities.
[0013]
【The invention's effect】
According to the present invention, the pile surface of the pile knitted fabric is constituted by the composite yarn exhibiting a complicated and fine crimp shape in addition to the spring-like crimp, so that the pile height, diameter and arrangement are irregular. It is possible to obtain a pile knitted fabric having a granular uneven appearance and having a novel uneven texture feel.
